I think you guys have seen this kind of errors before, but mine is special.
I have a few static libs in my Xcode project, when I tried to build it I got this error. But I have checked all my libs with command xcrun -sdk iphoneos lipo -info $libname, it gave me Architectures in the fat file: /Users/kiwi/Documents/Development/SourceCode/prj/lib.a are: armv7 i386 x86_64 arm64.
Undefined symbols for architecture armv7: "_SSLv2_server_method",
referenced from:

Has anyone had this issue on mac while installing boost or know how to fix? I seem to have everything together but this error. I am using OS X 10.10 & and Xcode 6.1.1.
This is what I used for the install and to make the framework.

I'm following this:
http://sadeepj.blogspot.com.br/2012/03/installing-and-configuring-opencv-to.html
I had a problem, compiling. But I already fixed it, modifying 2 files...
Now I'm trying to run that example.
And I get this error message:

I follows all steps already. And I can't even build it.
Please, help me.
[Before someone says that it is a duplicated post, I know it, here is the original one:
C++ linker errors with OpenCV.
I'm sorry. But I can't even comment on that one :/ ]
Wow, Finally solved:
Some considerations:
Realize that even it is looking for -l opencv_core.2.4.6, the
compiler will get the right file, if it is added correctly with other
name, in this case libopencv_core.2.4.dylib
I was adding the files with Project>Add files to... and then creating a group and dragging the files into the group. This was messing up the linkings in Project>Link Binary with Libraries. So I had to do it again by dragging the files in the group into that spot.
After theses things I had the situation where I had the two files (core and highgui) and 4 errors:

Then (thanks God and some days of googling) I got this:
Select your project, go to the Build Settings tab, filter by c++
standard library, and set this parameter to libstdc++ (GNU C++
standard library).

And finally it was sunny again in my code environment...
When trying to compile the following file in xcode:

I've been trying everything I can think off to resolve the issue but no joy. I've tried compiling for specific architectures (32 bit or 64), I've tried relinking all the libraries and other such measures like starting a new project and importing everything again.
Sounds like you need to rebuild libfreenect.
I'd suggest following the directions on this tutorial and once you have everything re-installed, run that nm test again and see if the symbols finally appear.
If they don't, grep through the library source and see if they are defined and simply conditionalized out for some reason.
